Adapter head for wells



Patented Sept. 3, 1946 Lester C. Hudson, Big Prairie, Ohio Application August 8, 1945, Serial No. 609,514

10 Claims.

The inventionrelates to wells, and more particularly to an adapter head for covering the well casing and supporting the well pipes and conmeeting the same to a pump.

The object of the invention is to provide a simple, inexpensive and easily operated head which materially facilitates the dependable suspension of the pipes within the Well casing.

Another object is to provide such a head with means for easily and readily connecting the same to a pump located at any angle around the adapter head.

A further object is to provide an adapter head formed of two parts comprising a base for covering the casing and supporting the outer well pipe and a head mounted upon and detachably con nected to the base for supporting the inner Well p1pe.

A still further object is to provide a combination adapter head of this character in which the head may be adjustably mounted in various po -sitions upon the base.

Still another object of the invention is to provide an adapter head of this character in which the upper ends of the outer and inner well pipes are screw threaded into the adapter.

A further object is to provide a brass lined packer seal upon the lower end of the outer well pipe supported by the adapter head.

A still further object is to provide such a brass lined packer seal having a tapered lower' end which will prevent the conventional jet, containing the nozzle and Venturi tube, carried by the inner well pipe from falling through the same and down into the well. v

It is still another object of the invention to provide a combination adapter head for use in connection witha two-pipe, jet, deep well pump.

A further object is to' provide a combination adapter head of the type referred to which facilia tates both the installation and servicing of deep well jet assemblies.

A still further object is to provide such an adapter head in which no pipe fittings are required at the top of the well to connect the down pipes in the well, or to connect the pipes leading from the adapter head to the pump.

Another object is to provide an adapter head of this character in which the head proper, to which the inner or smaller well pipe is connected, can be turned to six different positions to align with the pump without raising or moving the lower or base casting to which the larger or outer well pipe is attached.

Still another object is to provide such an adapter head with a removable, threaded plug, in the top of the upper casting or head proper, by means of which the well pipe may be filled with water for priming the pump.

It is a further object. of the invention to provide such an adapter head which eliminates the use of packing glands, brass fittings and well caps at the top of the well.

The above objects, together with others which will be apparent from the drawings, and following. description, or-which may be later referred to, may be attained by constructing the improved combination adapter head and packer sealin the manner illustrated in the accompanying drawings, in which;

Figure 1 is a vertical sectional view of the improved adapter head showing the manner in which the same is connected to the well pipes and to the pump;

Fig.2 is an enlarged top plan view of the improved head;

Fig. 3 an enlarged vertical. sectional View through the adapter head and portions of the casing and well pipes, and pipes to the pump; and.

Fig.4 an enlarged vertical sectional view of the improved brass lined packer seal used with the combination adapter head.

A two pipe jet, deep well pump of any conventional design is indicated generally at In and providedwith the usual suction or delivery pipe ll andpressure pipe !2. In ordinary practice these pipes are connected by elbows, fittings and the like .to the usual inner and outer pipes respectively of the well.

This requires an accurate cutting and fitting of the pipes and couplings and is objectionable because there is always danger of one or both of ,the well pipes being accidentally dropped into the well during the installation. Furthermore it is found that when such wells need servicing it is much more difficult to service the jet assembly than to install it.

The present invention contemplates an adapter head which overcomes these objections, beingv of simple construction so that it may be readily installed without danger of either of the well pipes dropping into the well, and so constructed that the jet assembly may be easily serviced when necessary.

The well casing is indicated at l3, and the improved adapter head to which the invention pertains includes the base, indicated generally at It and comprising a top wall l5 and conical skirt 16 adapted to fitover and cover the upper end of the casing I3 and rest upon' the ground line l1 preventing dirt, insects and the like from getting into the top of the casing.

A central opening i8 is formed in the top wall I of the base and surrounded by the depending,

annular, internally threaded flange 9 into which the upper end of the larger or outer well pipe is screwed.

After the pipe 20 has been connected to the base and lowered into the well and the base of the adapter has been positioned over the upper end of the casing, as shown in the drawings, the jet 2| of any conventional design such for instance as shown in Conery Patent No. 2,077,213 dated April 13, 1937 may be assembled upon the lower end of the inner or smaller well pipe 22 and the upper end of the pipe 22 connected to the upper casting 23 of the adapter head.

This upper casting or head proper, has a central passage 24 communicating with the larger or outer well pipe 20 and with the angularly disposed threaded bore 25 into which the adjacent end of the pressure pipe i2, leading to the pump, is screwed.

In the upper portion of the head 23 is located a central passage 26, communicating at its lower end with a threaded bore 21, into'which the upper end of the inner or smaller well pipe 22 is screwed and communicating with the'angularly disposed tapped bore 28 to which'the adjacent end of the suction pipe ll, leading to the pump, is adapted to be attached.

A threaded opening 29 in the top of the head 23 is arranged to be normally closed by a screw plug 30 "and is provided for priming the pump by removing the screw plug and filling the entire assembly with water.

By removing this screw plug and replacing it with a pipe nipple and pipe T-fitting, a hoist can be connected to the T-fitting for raising or lowering the inner or smaller pipe 22 out of or into the larger pipe.

When the pipe 22 has been connected to "the head 23, a gasket 31 is placed upon the top of the base casting l4 andthe pipe 22 is lowered into the outer pipe 20 and the head rotated to .the proper position to line up with the pump I0. bolts 32 being located through the flange 33 of the head casting 23 and into the base l4.

As there-are six of these bolts around the head it will be seen that six difierent adjustments of the head relative to the base are provided so as to assist in lining up'the headwith the pump. The pipes H and !2 are then screwed into place connecting the head with the pump.

Another feature of the invention is the brass lined packer seal 34 adapted to be attached to the larger or outer pipe 20 as by the coupling 35. This packer seal is in the form of a steel tube having brass lining 35 therein and having its lower end inwardly tapered as at 31 so as to prevent the jet2l from falling through the lower end of the outer pipe.

The brass lining reduces the inside diameter of the jet seal tube and provides a smooth surface to insert the leather packer rings 38 of the jet, this making a good seal which will last for years and also permitting the jet, with the inner pipe, to be easily removed at any time without permitting the leather seals to touch the sides of the largerpipe thus not damaging the leathers or causing themto stick within the outer pipe when inserting or removing the jet.

When the adapter head is thus assembled on the well and the pump it will be obvious that the outer pipe 20 of the well is connected to the pressure pipe 12 of the pump, and the inner pipe 2 of the well, to which the jet 2| is attached, is connected to the suction pipe I l of the pump,

Since the jet is connected to the lower end of the inner pipe 22 and provided with the packer rings 38 forming a seal between the lower ends of the well pipes, a flow passage is provided between the pipes for pressure fluid from the pressure pipe l2 of the pump to the jet.

In the normal operation of the pump as fluid is drawn into the pump through the suction pipe I l to be discharged from the pump to the usual tank or the like, a portion of the fluid is returned from the pump through the pressure pipe l2 to the space between the well pipes 20 and 22, this pressure fluid entering the jet 2| in usual and well known manner, creating a suction therein which draws fluid from the casing I3 upward through the jet and through the inner pipe 22 and suction pipe I I to the pump.
